There are 14 chromosomes in the ovum of a plant. How many DNA molecules are in the root of this plant before dividing?

Gametes or sex cells, like an egg, contain a haploid (single) set of chromosomes. And body cells or somatic cells have a diploid (double) set of chromosomes. Root cells are somatic cells, which means they have not 14, but 28 chromosomes. Each chromosome is made up of a DNA molecule.
But, just before the division, replication occurs in the cells, that is, the doubling of DNA molecules, which means that before division there will be 56 DNA molecules in the root cell of a given plant.
